Abstract: A semiconductor device comprises a layer of silicon (12) an insulating layer (11) and a bulk substrate (10), the insulating layer electrically insulating the silicon layer from the bulk substrate, the silicon layer having a conductive, non-contiguous sidewall (14), also insulated from the bulk substrate by the insulating layer. The semiconductive device has improved radiation tolerance due to peripheral shielding by the biasable conductive sidewall.

Abstract: A latch mechanism for a door of the like includes first and second rotatable latch operating members (20,22) which operate a latching bolt or the like. An axially movable square section spindle (16) extends through complementary holes in both members. In an engaged position, the spindle operates both members when rotated. In a disengaged position, a circular section portion (34) of the spindle registers with a hole in one of the members (22). In the disengaged position the bolt can be operated by the first member (20) even though the second member may be prevented from rotating by means of pins(28). The spindle (16) can be moved between engaged and disengaged positions by a push-rod extending out of the door. Thus, when the second member is locked it may be overridden by actuation of the rod and the first member.

Abstract: This invention relates to improvements in Radar Transponder in which unnecessary waveguide electro­magnetic field modes are not generated. More particularly, since a radar transponder is configurated so as to connect its amplifying means and detecting means via a metal body having resilience on the antenna housing, the volume of the waveguide becomes more smaller than that of the conventional one. According to the composition as described above, it is possible that the cut-off frequency is set higher than the frequency of the required band. Therefore, unnecessary waveguide electromagnetic field modes are not generated.

Abstract: A process for improving the stability of a polyarylate resin by reducing the terminal carboxyl acid group concentration of the polyarylate resin, the process being comprised of melting a mixture of the polyarylate resin and an aromatic carbonate capping agent and reacting the mixture under heat and, if necessary, vacuum until the concentration of the terminal carboxyl acid groups is reduced to less than that of the polyarylate resin prior to end-capping. The process also results in a polyarylate resin with a decreased flammability rating when the aromatic carbonate capping agent is bromine substituted.

Abstract: In a method for welding profiles (1, 2), particularly plastic profiles for windows, doors or the like, the two profile regions to be welded to each other are heated to welding temperature and joined together after heating. This involves heating the end face (1a) of the first profile and heating the surface (2a) running transversely thereto of the second profile (2). The heating of the second profile (2) is confined to a surface region which corresponds in position and shape to the end face of the first profile. The profiling of the surface of the second profile coincides at least partially with the end face profiling of the first profile. With this method, it is possible to weld differently shaped profiles, particularly plastic profiles, tightly to each other. <IMAGE>

Abstract: A method for operating a secure, single-channel signal transmission interface is indicated, in which, along with a cyclic code for data security and non-equivalent duplicate transmission of the data telegrams, a cyclic change of all transmitter-side processors (R1, R2, R3; R4, R5, R6) is provided in the data telegram output. An identification code of the source processor inserted into the individual data telegrams enables the processor change to be checked on the receiving side. This ensures that redundant circuit components on the transmitting side are regularly put into operation and checked. The disclosure time for errors in these circuit components is reduced and with it the probability of occurrence of duplicate errors. A message number in each data telegram allows the sequence of the information to be transmitted to be checked and deviations from this sequence, for example in the case of repetitions of incorrectly transmitted data telegrams, to be prevented. <IMAGE>

Abstract: Full duplex operation is achieved in a lightwave communication system by employing terminals having a distributed Bragg reflector (DBR) laser having separate electrically controllable Bragg reflector and gain sections. While operating as the basic heterodyne reception element, the DBR laser simultaneously generates lightwave signals for transmission to other terminals. External circuits process the electrical (intermediate frequency) signals from the simultaneously modulated and signal mixing laser to extract received information.

Abstract: This is an electronic scheme for correcting for mechanical misalignment (41) and chromatic aberrations (42) from laser beam to laser beam in the scan direction of a multiple beam laser scanning system for use in an electrophotographic machine. Each beam is first corrected for mechanical misalignment and thereafter for chromatic aberrations. A reference laser beam produces two pulses near the start of scan (SOS) and two pulses near the end of scan (EOS). A non-reference laser beam then produces SOS and EOS pulses from which the mechanical misalignment is calculated. A gated clock is energized by the reference pulse and a tapped delay line is used for nanosecond resolution. After accomplishing correction for mechanical misalignment, chromatic aberrations are correctected by measuring the amount of total pel displacement of the non-reference scan line relative to the reference scan line and inserting appropriate delays at selected intervals throughout the non-reference scan in order to maintain pel placement accuracy to a desired tolerance.
